This product is a high-speed isolated RS-485 transceiver with integrated transformer driver.
The ADM2485 is a galvanically isolated RS‑485/RS‑422 transceiver that combines a three‑channel isolator, differential line driver, and receiver in a single 16‑lead SOIC package. It operates from 5 V or 3.3 V logic supplies and provides an isolated 5 V bus side supply.
The device meets industrial standards such as ANSI/TIA/EIA‑RS‑485‑A‑98, ISO 8482, UL 1577 and VDE certifications, offering high common‑mode transient immunity and built‑in thermal shutdown protection for robust field‑bus applications.
